Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | NVIDIA - GeForce RTX 5070 | AMD - Radeon RX 9070 |
|---|---|---|
| CUDA / Stream cores | 6144 | 3584 |
| VRAM | 12 GB | 16 GB |
| Memory bus | 192 bit | 256 bit |
| TDP | 250 W | 220 W |
| Ray tracing cores | 48 | 56 |
| DLSS | true | false |
Between the GeForce RTX 5070 and Radeon RX 9070, the GeForce RTX 5070 comes out ahead in cuda / stream cores / dlss, while the Radeon RX 9070 wins on vram / memory bus. Overall, the GeForce RTX 5070 scores 63.9 and the Radeon RX 9070 scores 64.9 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (63.9 vs 64.9). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.
Pick the GeForce RTX 5070 if you care most about cuda / stream cores / dlss. The biggest gaps in its favor are cuda / stream cores, dlss. The single most decisive one: CUDA / Stream cores — 71.43% more. 6144 vs 3584.
Pick the Radeon RX 9070 if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are vram, memory bus, tdp, among others. The single most decisive one: VRAM — 33.33% more. 16 GB vs 12 GB.
Both ship with comparable 3dmark time spy, so those specs do not separate the two — focus on the differences below.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
Which should you buy: NVIDIA - GeForce RTX 5070 or AMD - Radeon RX 9070?
AMD - Radeon RX 9070 leads the current Mars Score by 1.0 points.The more useful decision is the trade-off behind that result: compare vram, cuda / stream cores, boost clock, tdp against the way you will actually use the product.
